Day Three suggests that although a slight increase by +0.2% points to 45.8% for Leave, Remain saw the biggest shift, up by +0.4% - back to the same rate at the close of last week. The ORB poll was the only change pushing its Remain votes past 50%, closing the gap from a 1.8% difference to 1.6% going into tomorrows vote. Meanwhile, the bookies continued to favour Remain with practically all bookmakers sharing the same odds.

The polls remain too tight to call as voting opens at 7am tomorrow morning, and will stay open until 10pm. The results are expected to be announced some time Friday 24 June.
